Advanced Engineering Materials, EarlyView.This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Is It Possible to Wage a War without Warriors? The Effects of Robotisation in Small Wars
Czech Journal of International Relations, 2010 At present, Western armies seem to be engaged only in small wars, e. g. the war in Afghanistan and Iraq, and this trend is likely to continue in the near future.

Frankenstein: The United States in Afghanistan during the 1980s and 1990s [PDF]
, 2017 For nearly the past quarter century, the United States has been involved in covert operations in a region of the world that most people could not locate on a map. Invisible wars being fought by the United States and other foreign intelligence agencies in

Advanced Engineering Materials, EarlyView.Through direct application of porous transport layer (PTL) on the bipolar plate (BPP) with thermal spraying, the interfacial contact resistance is improved. With the cold gas sprayed BPP–PTL coating system, a proton exchange membrane water electrolysis cell with a cell voltage of Ucell = 1.9 V can be operated up to i = 2.5 A/cm2 in a dynamic mode ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

The Spiral of Prejudice and the Securitization of Migration
Italian Political Science, 2021 The post-Cold War world has witnessed increased migratory movements. In many countries, prejudice has entailed negative developments in dealing with the phenomenon, spawning a series of insecurities and resulting in more irregularities that do not ...

Japan’s Coast Guard Capacity Building under Abe Shinzō: Between Power, Money and Norms
International Quarterly for Asian StudiesFor Japan’s former prime minister Abe Shinzō, security cooperation with Southeast Asia was central to preventing the South China Sea from turning into a “Lake Beijing” – completely under Chinese control. This paper explains why Abe’s security engagement

Advanced Engineering Materials, EarlyView.This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.
